Pioneer 11 HVM Magnetometer Reduced Data Records - JPL Digital Data Preservation


Availability: At NSSDC, Ready for Offline Distribution (or Staging if Digital)

Time span: 1973-05-20 to 1973-08-18


This data set for Pioneer 11 Magnetometer Reduced Data Records (RDRs) has been generated by the Science Digital Data Preservation Task (SDDPT) at the Jet Propulsion Laboratory (JPL). Each volume in the data set includes ancillary information in addition to instrument data in RDR format. The RDR data are in a low level format which is unlikely to be interpretable by general users; no documentation on this format is currently available at NSSDC. Data from each original magnetic tape has been written in separate directories on compact disks at JPL. A log file documents SDDPT processing history for each original tape. No change has been made in the original data format other than copying to compact disk by the ISO 9660 level 1 Interchange Standard to assure accessibility from a variety of operating systems. File attributes are specified by Extended Attribute Records (XARs). Details on the directory structure and contents are in the aareadme.txt file on each volume. The text file 328_info.txt in the index directory lists the data volumes and, in some cases, the label information on date coverage, which varies from daily early in the mission to weekly at later times. The Pioneer HVM experiment team should be contacted for more information on this data set.
